Polarization Rotation Drives a Spin-Topological Transition in Ferroelectric Bismuth Monolayer
Jinming Zhai, Lingzhi Cao, Yateng Wang +4
Bismuth monolayer is the first two-dimensional elemental ferroelectric and an appealing platform for coupling polar order to spin-orbit-driven topology. However, its microscopic sw…
Weak Polar Optical Phonon Scattering Decouples Electron and Phonon Transport in Layered Thermoelectric Materials
Zhonghao Xia, Michele Reticcioli, Yateng Wang +3
High-performance thermoelectric (TE) materials are crucial for efficient waste-heat recovery and solid-state cooling technologies. A persistent challenge in TE materials design ari…
Microscopic Origin of the Ultralow Lattice Thermal Conductivity in Vacancy-Ordered Halide Double Perovskites Cs ( = Zr, Pd, Sn, Te, Hf, and Pt; = Cl, Br, and I)
Lingzhi Cao, Yateng Wang, Zhonghao Xia +1
Vacancy-ordered halide double perovskites Cs have recently attracted significant attention due to their intrinsically ultralow lattice thermal conductivity ($κ_{\mathrm{L}…
Stacking effects on magnetic, vibrational, and optical properties of CrSBr bilayers
Huicong Li, Yali Yang, Zhonghao Xia +4
The van der Waals layered semiconductor CrSBr, which exhibits A-type antiferromagnetism and a relatively high Néel temperature, has been successfully exfoliated into atomically th…
